Answer:
g(x) = 3x² + 8
Step-by-step explanation:
Let f(x) = 3x² + 5
Now, the given function f(x) is translated up by 3 units and is equal to g(x)
And according to the rule of translation , if the graph of a function f(x) is to be translated up by c units then the equation becomes f(x) + c
Since, the graph is translated by 3 units
⇒ g(x) = f(x) + 3
⇒ g(x) = 3x² + 5 + 3
⇒ g(x) = 3x² + 8
Translating the function 3 units up, we will get g(x) = 3x^2 + 8
How do translations work?
There are two general types of translations.
Horizontal translation:
For a general function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N).
- If N is positive, the shift is to the left.
- If N is negative, the shift is to the right.
Vertical translation:
For a general function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N.
- If N is positive, the shift is upwards.
- If N is negative, the shift is downwards.
Here we start with the function:
f(x) = 3x^2 + 5
And then we translate it up 3 units, then the function g(x) will be:
g(x) = 3x^2 + 5 + 3
g(x) = 3x^2 + 8
